SPECIFICATION forming part of Letters Patent No. 626,224, dated June 6, 1899. Application filed January 30, 1899. Serial No. 703,771. (No model.)

To (oZZ whom it may concern.-

Be it known that I, IRA CROCKER, a citizen of the United States, residing at Portland, in the county of Cumberland and State of Maine, have invented certain new and useful linprovements in Anchors; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to anchors having a removable stock, such stocks having hitherto been held in place within the opening in the shank by means of a shoulder located upon one side of the shank and a key set in a slot in the stock upon the other side of the shank. Thus constructed the anchor is found inconvenient in use by reason of the frequent loss of the key, of its rusting into the slot or becoming broken, and because of the weakening of the stock by the insertion of the slot.

My improvement consists in a novel in ethod of locking the stock by which these disadvantages are obviated.

In the drawings, Figure 1 is a perspective view. Fig. 2 is a front elevation of the upper part of the shank and part of the stock. Fig. 3 is a detail showing in side elevation the upper part of the shank and strap with the shackle in place; Fig. 4, a detail showing in side elevation the top of the shank with the strap unlocked. Fig. 5 is a detail showing in side elevation the upper part of the stock. Fig. 6 is a side elevation of the strap; and Fig. 7 is a section of the shank, strap, and stock.

The shank a has the ordinary arms Z) and flukes c. The upper part of the shank is provided with a keyhole-slot d of the shape shown in Fig. 5, the lower walls of the lower part widening as they approach the bottom.

The strap a is of the shape shown in Figs. 1, 2, and 6, the lower ends being provided with a keyhole-slot f, the circular part of which is described upon the same radius as the circular portion of the slot cl, while the walls of the lower part are parallel with the centralline or axis of the shank. (See Fig. 6.)

The stock 9 is of the ordinary construction, except that it is provided upon the under side with a rib h and tongue 2'. The distance between the shoulderl (which is of the ordinary construction) and the edge of the rib h is equal to the extreme width of the strap, while the tongue i is centrally located between these two points and is equal in width to the distance between the inner sides of the strap a. The strap 6 may be provided withashackle m, (see Figs. 1 and 3,) to which is attached the cable at, or the cable may be bent directly upon the strap. The strap eis placed outside the shank a, and the shackle m being removed or the cable being unbent the loop of the strap is brought down against the shank C6 in the position shown in Fig. 4, the circular portions of the apertures (Z and fregisterin g. The stock is now passed through the circular openings until the shoulder Z comes in contact with the sides of the strap, the registering of the lower portions of the holes (:1 and f permitting the passage of the rib h and tongue 2;. The strap is now turned upward, the shackle connected in the usual manner, and the anchor is now ready for use. To remove the stock or change its position to that shown in Fig. 2, it is necessary to remove the shackle or cable in order to permit the strap to assume the position shown in Fig. 4, when and only when the stock can be withdrawn or changed in position. The shackle m or cable when connected with the loop of the strap, as shown in Fig. 3, has the effect of locking the device and prevents the strap 6 from lying sufficiently close to the shank a to permit the lower parts of the apertures d and f to register, which is only possible when the upper portion or loop of the strap lies in contact with the side of the shank, as shown in Fig. 4. i

What I claim is- 1. In an anchor the combination of a shank and a strap both being provided with a circular opening with elongated slots, said slots being capable of registering only when the loop of the strap is in contact with the shank, with a stock provided with a shoulder and with a rib adapted to pass through the elongation of the slots when registering, substantially as described.

2. In an anchor the com binationof a shank and a strap each being provided with a circular opening with elongated slots, said slots being capable of registering only when the loop of the strap is in contact with the shank,

too

with a stock providedvwith a shoulder and with a rib adapted to pass through the elongation of the slots when registering, and a cable or shackle attached to the strap, substantially as described.

7 3. In an anchor, the combination of a shank y with a strap with circular openings and elongated slots adapted to register in one position only, and a stock having a rib suited to pass through said elongations of the slots when registering, together with a cable or shackle attached to the strap, substantially as described.

4. In an anchor, the combination of the shank and a strap each having circular open ings with elongated slots adapted to register when the strap is in one position only, 7 a stock having a rib and tongue adapted to pass through the elongations of the slots when registering, together with a cable or shackle attached to the strap,substantially as described. In testimony that I claim the foregoing as my invention I have hereunto set my hand this 30th day of December, A. D. 1898.
